The Gulfstream jet touched down at 12:11 p.m. (2011 GMT) at Hillsboro, Oregon, airport, the same airport where it had taken off bound for Toronto around five hours earlier.

Neither Nike co-founder Phil Knight nor any sports stars were on board, a Federal Aviation Administration spokesman said. But a Nike official who spoke on condition of anonymity said Nike President and CEO William D. Perez was among those on board the Gulfstream V jet.

Vada Manager, a Nike spokesman, said the seven on board were three senior executives, a fourth Nike employee and three crew members. Nike is the world's largest athletic shoe and clothing company.
